Spr marketing has launched a range of carton sealers manufactured by s s industries, new delhi. Model ssfa [hot melt] is an adjustable pre-set fully automatic carton sealing machine with an automatic flap closer. The carton sealer does not require any operator and can be attached at the end of the line for online flap closing and carton sealing with hot melt glue. It takes bottom sealed loaded cartons from the conveyor system automatically and indexes them into the top flap folding section and hot glue spray/application section, after which the cartons are guided to the dressing section for sealine. The indexing system is controlled electronically and pneumatically and releases cartons one by one to the flap folding and hot glue spray section where the flaps perpendicular to the direction of movement of cartons are folded and hot melt glue is sprayed from the hot glue system for fraction of a second by hose and gun. After this the flaps parallel to the movement of cartons are folded, and the cartons pushed by guide rods to the pressing section, which contains top rollers to press the top flaps for perfect sealing, and side guide rollers to ensure proper centering while binding and for smooth movement.
